SERVICE & MAINTENANCE
Note:
Before carrying out any repair, inspection, or maintenance operations, check that you have applied the
parking brake, lowered the forks to floor level and removed the key from the switch. Always pull the plug out
of the battery before carrying out any operations on the electrical system.
For general cleaning of the Forklift, use dry air and damp rags; never use pressure washing, solvents, or
gasoline to avoid damage to Forklift components equipment.
Maintenance and inspection should be carried every 10 hours. If the Forklift is used frequently, the interval of
maintenance must be shortened.
Warning: The inspection, maintenance, adjustment and repair operations must be carried out by
qualified and authorized personnel onl y .
Connect the battery only when necessary for testing.
Take all the necessary precautions and other measures when carrying out any maintenance, adjustment,
repair & inspection and when the drive wheel is raised off the ground.
The Usage and Maintain of the Storage Battery
The safety rules of the battery
Remember that the battery generates gases that may cause it to explode on contact with flames or sparks.
(1) Connections must be coated with anti-acid grease or neutral Vaseline.
(2) Do not tap current from the battery with plugs or clips for makeshift contacts.
(3) Check whether the plastic protections of the connections are positioned correctly.
(4) No smoking should be allowed when repairing a battery or while it is charging.
(5) Never rest tools or metal parts on the battery.
(6) Keep the metal cowling of the batteries clean and dry.
Checking the electrolyte in the battery
The most important thing to be carried out on the battery is measurement of the density of the electrolyte as this indi-
cates the state of the charge.
The density of the electrolyte is measured with a density meter by inserting this in the element to be measured and
tapping a sufficient quantity of electrolyte to bring the float to the surface. Read the value from the specific weight piece
in the density meter. The density of a completely charged element is around 1:1.27~1:1.28 at 20~25°C. Density drops
as the battery runs down. Running down of the battery must be interrupted when the density of the electrolyte reaches
1:1.25. If the temperature of the electrolyte is other than 25°C when the check is made, the value drops by approx. 7g/l
for an increase of 10°C.
Top up the electrolyte
The electrolyte used in lead batteries is a solution of sulfuric acid in distilled or demineralized water.
A drop in the level of the solution in the elements is normal. This is caused partly by evaporation and partly by the elec -
trolysis that occurs during the final charging phase. One of the most important maintenance operations on the battery is
therefore topping up of the water to keep the level of the solution required. Follow the rules indicated below:
• Always use distilled or demineralized water.
• Keep the level approx. 10mm slightly above the element.
• Do not use tap water or pure water.
• Do not overfill, avoid spilling of the acid that causes reduction of element capacity.
